る。FIG. 1 is based on three measures of (1), (2) and (3). (1) A mechanism and container that fixes the device to the foundation (main structure), protects the internal device, and prevents the upper unit to which the upper structure is fixed from falling off. (2) responds to the sway of the omnidirectional roll by the upper convex curved unit sliding on the lower unit surface having a different concave curved surface. At this time, a downward force is generated in the portion (3). Each cushioning material of the lower unit responds to the generated downward force by both compression and tension. That is, when the projection of the lower unit slides downward (upward on the opposite side) in the groove for vertical movement of the container, a reaction force is generated in each cushioning material, generating a restoring force and causing the upper unit to move to the origin. To return to.

復帰させる事も可能である。FIG. 5 slides on the curved surface 5 of the lower unit along the curved surface of the lower unit 2U-1. At this time, a downward force is generated. The cushioning material 7 of the lower unit reacts to the generated downward force. That is, when the projection 9 of the lower unit slides downward (upward on the opposite side) in the groove 6 for vertical movement of the container, a reaction force of compression and tension is generated in each cushioning material, and a temporary lowering A combined restoring force is generated with the reservoir. After the vibration, the protrusion 4 of the upper unit slides along the groove 3 of the lower unit and returns to the origin. In addition, according to the scale of the upper structure, setting of the upper and lower unit curvature surface,
Considering the material setting (strength, lubricity, weather resistance) and the lower unit cushioning material restoring force (strength, material, method),
Even without the protrusions 4 and the grooves 3, the load center of gravity can be reliably returned to the origin.
